Saki Takagi is a woman wearing an exciting one-piece dress with a plunging neckline. Her eyes are taken away by her plump breasts... She usually works at an advertising agency as the president's secretary. She likes sex, and she was somehow interested in it, so she decided to appear in it. She often watches AV on a regular basis, and she uses it as a side dish for masturbation and as a teaching material for sex.
